1. INTRODUCTION

1.1 Overview

These models are advanced line-interactive simulated sinewave
uninterruptible power systems (UPS) designed to prevent spikes, surges, sags,
transients and blackouts from reaching your sensitive equipment. Your
equipment may include such items as computers and computerized
instruments to telecommunication systems. When AC power is present, the
UPS filters and conditions the power continuously. When AC power fails, the
unit employs its internal maintenance-free battery to supply back-up power
without interruption.

1.2 Frequency Auto Sensing

The ES models can operate in either a 50 or 60 Hz environment. When you
plug the UPS into an AC outlet and turn it on, it will automatically detect the
incoming line frequency and configure itself to match that frequency.

1.3 Smart Buck and Boost Line Conditioning

The voltage from your AC power source can fluctuate above and below the
standard rating. This microprocessor controlled UPS provides line conditioning
via both buck (step-down voltage) and boost (step-up voltage) functions. For
example, if your normal voltage is 120V and the voltage fluctuates up to 135V,
the buck function in your UPS will step it down so that your equipment receives
approximately 120V. If the voltage fluctuates down to 105V, the boost function
will step it up so that your equipment receives approximately 120V. This
provides your equipment with excellent voltage regulation with less possibility
for the UPS to drain its internal battery.

1.4 User Replaceable Battery Design

The battery is the most critical part in a UPS. The average lifetime of a battery
is between 3 and 5 years. The special user-replaceable battery design of this
UPS provides significant savings and gives the UPS an almost unlimited life.
You can replace the battery very easily, and without turning off your UPS or
the equipment it is protecting.

1.5 Advanced Interface to Communicate with Computer

Many UPS’s provide only a basic power failure warning. These models,
together with OPTI-SAFE Xtreme also provide you with important operating
information. From your computer screen, you can know input/output voltage
and current, frequency, battery voltage, etc., and analyze power problems. If
software is not part of your UPS package, you can purchase it from your local
dealer.

1.6 Schedule Shutdown & Startup

Using software you can locally or remotely control the shutdown and startup of
equipment connected to the UPS. A customized schedule can be developed to
meet your specific requirements.

1.7 Data-Line Surge Protection

The built-in data-line surge suppression on the rear panel completes your
system protection. It provides an easy way to protect a network (RJ45) or
modem (single line phone) connection from hazardous spikes.

3.2 Placement

1. This unit is intended for indoor use only. Although your UPS is very
rugged, its internal components are not sealed from the environment.

2. T he UPS must be installed in a protected environment away from heat­emitting appliances such as a radiator or heater. Do not install this product
where excessive moisture is present.

3. The location should provide adequate air flow around the UPS with one
inch minimum clearance on all sides for proper ventilation.

9

3.3 Determining How Much Equipment You Can Connect to Your UPS

1. Make a list of all equipment that requires protection.

2. Each piece of equipment has voltage and current (VA) ratings printed on
the back label (see examples below). Your equipment may have a voltage
rating such as 88-264V. Since the standard voltage in the United States is
120V, you should use 120V in your calculations.

ViewSonic G81 0
120V 2.7A
50 / 60 Hz
SN: Q771515388

Computer Co
Pentium Pro 200MHz
120V 2.0A
50/60 Hz
SN: 123456

3. Multiply the voltage and current of each piece of equipment (VA
requirements); for example, 120V x 2.7A = 324VA, 120V x 2.0A = 240VA.

Add up the VA requirements for each device; for example, 324VA +

240VA = 564VA.

4. Make sure that your UPS has at least as much VA capacity as your

equipment requires.

3.4 Powering Up Your UPS

1. For 110/120V versions, connect the power cord to a verified grounded 3­wire receptacle. For 2X0V versions, please refer to Sec 3.5.

2. Power up the UPS by pressing the On/Off button for 3 seconds.

3. We recommend that you charge the battery for six (6) hours before
first use of your UPS. You may use the UPS immediately without

charging the battery, but the backup time may be less than the rating. The
UPS recharges the battery automatically whenever AC power is available.

3.5 Connecting Your Equipment to the UPS

1. For all UPS models except the 2xxV versions: connect the power cord(s)
of your computer equipment to the output receptacle(s) of the UPS.
Switch on the computer equipment.

2. For 2xxV versions, as shown in the illustration below: connect the input
power cord of your computer equipment to the inlet of the UPS and the
wall socket. Use the power cord supplied with the UPS to connect from
the outlet of the UPS to your equipment. Switch on the computer
equipment.
